I think this is cool and definitely says something: Even if you’re
writing brand new code, which can be entirely designed for testability
(if that’s what you want), at some point you’re going to have to
interface with something you didn’t write (SharePoint, .NET Framework)
and you’re still going to want to test that interface code, which is
where Isolator comes in. I’m so glad they’ve got an open source license
now!
